Really for a 2 day hike its probably more than enough food (and I guarantee I'll be sick of it the first day) but it has adequate shelf life and has got the calories. and as ark pointed out, no prep. anything that requires prep means time wasted when I should be getting home as quick as possible. also why I prefer bottles of water (rotated more frequently) rather than a lot of filters, though I do have a filter in the bag. searching for water is another one of those things i'd rather not waste time on unless I had to.
